Kosky to tell Cabinet details of Melbourne's train crisis

Victoria's Public Transport Minister Lynne Kosky will report to Cabinet today on the problems with Melbourne's train network.

Ms Kosky was overseas when the crisis started, and returned from leave early to hold talks with transport officials and Connex yesterday.

The rail operator has removed 31 of its Siemens trains from service while it investigates the cause of braking problems.

Ms Kosky says it is still not clear when the trains will be returned.

"Until they've met the safety requirements those trains won't be returning to the system, the primary concern is people's safety and then of course it is to get the trains back into the system, but safety is number one," she said.
